The bummer is we still don’t have it working with vBulletin 4.x. So we’re looking for someone to step up and see if we can make this work. Ideally someone who has worked with VB before and has some knowledge of how SSO works. Canonical can provide access to a license, so if you have any leads on someone who can do this, or if you can do it, let me know and we’ll get started!
